Since this is a hugely mis-understood subject that seems to come up multiple times a week:

Gifter: They don’t pay any tax until they exceed $12.06M in their lifetime. They have to report gifts over $16k in a given tax year but it’s not taxed.

Receiver: Never pays gift or income tax on gifts. Doesn’t matter how large the gift is.
